Encapsulation and Data Abstraction In OOP

By -
Encapsulation is a mechanism that associates the code and the data it manipulates and keeps them safe from external interference and misuse. Creating new data types using encapsulated-Items that are well suited to an application to be programmed is known as data abstraction. The data types created by the data abstraction process are known as Abstraction process are known as Abstract Data Types. Data abstraction is a powerful technique, and its proper usage will result optimal, more readable, and flexible programs.

The use of encapsulation in protecting the members of a class from unauthorized access is a good programming practice; it enforces the separation between the specification and implementation of abstract data types, and it enables the debugging of programs easily.

    Encapsulation and Data Abstraction are two fundamental principles of Object-Oriented Programming (OOP) that improve software security, maintainability, and modularity. Encapsulation is the process of combining data (attributes) and the methods (functions) that operate on that data into a single unit called a class. It also restricts direct access to an object's internal data by using access modifiers such as private, protected, and public. Data is typically accessed and modified through public methods (getters and setters), ensuring controlled access and protecting the object's integrity.

    Data Abstraction focuses on hiding the internal implementation details of an object while exposing only the essential functionality to the user. This allows developers to interact with an object through a simple interface without needing to understand its underlying complexity. Abstraction is commonly implemented using abstract classes and interfaces, enabling multiple implementations while maintaining a consistent interface. Big Data Projects.Together, encapsulation and abstraction promote code reusability, reduce system complexity, improve security, and make software applications easier to develop, test, and maintain. These concepts form the foundation of modern object-oriented languages such as Java, C++, Python, and C#.

Reusability In OOP

By -
Image
  In OOP, The concept of inheritance provide the idea of reusability. This means that we can add additional features to an existing class without modifying it. This is possible by deriving a new class from the existing one. The new class will have the combined features of both the classes. The real appeal and power of the inheritance mechanism is that it allows the programmer to reuse a class that is almost, but not exactly, what he wants, and to tailor the class in such a way that it does not introduce any undesirable side effects into the rest of the classes.  Fig.5 : Property inheritance Note that each sub class defines only those features that are unique to it. Without the use of classification, each class would have to explicitly include all of its features.

Difference Between Functional And OOP approach

Difference  Between Functional & OOP approach         Conventional Programming, Using high Level Languages such as COBOL, FORTRAN and C, is commonly Known as procedure-oriented programming(POP) , In the procedure-oriented approach, the problem is viewed as  a sequence of things to be done such as reading calculating and printing. A number of functions are written to accomplish these tasks. The primary focus is on functions. A typical Program structure for procedural programming is shown in Fig, 1, The technique of hierarchical decomposition has been used to specify the tasks to be completed for solving a problem.  Fig. : Typical structure of procedure-oriented programs Procedure-Oriented programming basically consists of writing a list of instruction for the computer to follow, and organizing these instructions into groups known as functions. We normally use of flowchart to organize these actions and represent the flow of c...
